The book argues that international investment law is a structured body of law based on uniform principles of investment protection.

Transnational investment involves a variety of actors (States, public and private legal entities, and natural persons) whose relationships are governed by rules and legal instruments belonging to different legal systems. This book provides a systematic study of the sources of rights and obligations in the field of transnational investment, and their coordination and interaction. It focuses primarily on the network of over 3,000 Bilateral Investment Treaties, international investment contracts, customary international law, the main multilateral treaties, national legislation, international case law and general principles of law. The book, firmly based on State practice, arbitral awards and national decisions, is indispensable to fully appraise the nature and content of the claims of private investors as well as to identify the law applicable in investment arbitration.

Bringing together conceptual theories of international investment law with the practical application of the law in treaty arbitration, this book investigates the key controversies in the field. It provides a detailed examination of how a different theoretical approach would have led to a different outcome in a number of important arbitral awards.

Concise introduction to the dynamic field of international investment law which sets out the key legal concepts and engages with current debates.

This monograph offers a detailed and distinctive analysis of corporate nationality under international investment law, covering the ICSID Convention and the investment treaty framework. It takes the reader back to the basics, threading through the concepts of jurisdiction, nationality, and corporate personality to give a clear context to the discussion of corporate nationality under international investment law, at a time when international investment is dominated by multinational business enterprises operating in a globalised economy. The book examines different understandings of corporate personality and nationality under a selection of jurisdictions and public international law. It also offers an in-depth analysis of approaches found in ICSID arbitral awards and in investment treaty practice, distilling the problematic areas and discussing the impacts of the areas of concern. It evaluates the techniques developed to address problems and puts forward suggestions for effective and balanced solutions to the questions of corporate nationality and personal scope of investment protection.

Analyses bilateral treaties and regional agreements on foreign investments, focussing particularly on measures taken in the context of economic crises.

This book presents the first critical review of the less frequently addressed stakeholders in international investment law. Focusing on private actors, including but not limited to lawyers, experts, funders, civil society, the media and scholars, the book highlights the variety of actors that help shape international investment law and demonstrates how best to manage their interactions in order to achieve synergies and enhance the legitimacy of this pluralistic field.

International investment law is one of the most dynamic fields of international law, and yet it has been criticised for failing to strike a fair balance between private and public interests. In this valuable contribution to the current debate, Valentina Vadi examines the merits and pitfalls of arbitral tribunals’ use of the concepts of proportionality and reasonableness to review the compatibility of a state’s regulatory actions with its obligations under international investment law.

This book examines the issue of foreign investor misconduct in modern international investment law, focusing on the approach that international investment law as it currently operates has developed towards foreign investor misconduct. The term ‘misconduct’ is not a legal notion, but is used to describe a certain phenomenon, namely, a group/class of actions. This term is convenient since it makes it possible to introduce and describe the phenomenon as such, without a division into concrete types of conduct, like ‘abuse of process’, ‘violation of national law’, ‘corruption’, ‘investment contrary to international norms and standards’, etc. The term ‘misconduct’ is intended to embrace various kinds of conduct on the part of foreign investors that the system of international investment law does not accept – such as that which it regards as illegal, against public policy, or otherwise inappropriate – and triggers legal consequences. Rarely, however, does international investment law clearly articulate what it considers unacceptable investor conduct, and certainly not in any systematic fashion. As such, this book addresses the following questions: What types of investors’ conduct are legally unacceptable? What mechanisms are available to deal with unacceptable investors’ conduct, and what are the legal consequences?

International investment law is in transition. Whereas the prevailing mindset has always been the protection of the economic interests of individual investors, new developments in international investment law have brought about a paradigm shift. There is now more than ever before an interest in a more inclusive, transparent, and public regime. Shifting Paradigms in International Investment Law addresses these changes against the background of the UNCTAD framework to reform investment treaties. The book analyses how the investment treaty regime has changed and how it ought to be changing to reconcile private property interests and the state's duty to regulate in the public interest. In doing so, the volume tracks attempts in international investment law to recalibrate itself towards a more balanced, less isolated, and increasingly diversified regime. The individual chapters of this edited volume address the contents of investment agreements, the system of dispute settlement, the interrelation of investment agreements with other areas of public international law, constitutional questions, and new regional perspectives from Europe, South Africa, the Pacific Rim Region, and Latin America. Together they provide an invaluable resource for scholars, practitioners, and policymakers.
